Does not redirect with previous URL

Hi there,

When accessing a wp-admin page while not logged in, it doesn’t keep the old URL and redirect to the new login URL.

The normal behaviour is to add a redirect_to GET parameter in the URL so that it can take you directly to a post edit page for example.

Tried to implement it myself, but no hook available to do it without hacking the plugin if I’m right.

It’s a bit dirty, I think it’s better if you can handle this directly.

public function wp_loaded() {

		global $pagenow;

		$request = parse_url( rawurldecode( $_SERVER['REQUEST_URI'] ) );

		if ( ! ( isset( $_GET['action'] ) && $_GET['action'] === 'postpass' && isset( $_POST['post_password'] ) ) ) {

			if ( is_admin() && ! is_user_logged_in() && ! defined( 'DOING_AJAX' ) && $pagenow !== 'admin-post.php' && $request['path'] !== '/wp-admin/options.php' ) {

				$redirect_to = home_url();
				if ( ! empty( $request['path'] ) ) {
					$redirect_to .= $request['path'];
				}
				if ( ! empty( $request['query'] ) ) {
					$redirect_to .= '?' . $request['query'];
				}

				wp_safe_redirect( $this->new_redirect_url( $redirect_to ) );
// .... 

public function  new_redirect_url( $scheme = null ) {

		if ( get_option( 'permalink_structure' ) ) {

			$url = $this->user_trailingslashit( home_url( '/', $scheme ) . $this->new_redirect_slug() );
			if ( ! empty( $scheme ) ) {
				$url .= '?redirect_to=' . urlencode( $scheme );
			}

			return $url;
